INSUFFLATOR.

SPECIFICATION forming-part of Letters Patent No. 658,436, dated September 25, 1900.

Amhcation 5 5 2 1900, serial No. 18,266. (No model.)

To (DZ/Z whom it may concern Be it known that I, HANS HENNERIOH GROTH, a citizen of the United States, residing at Cincinnati, in the countyof Hamilton and State of Ohio, have inventedcertain new and useful Improvements in Iusufi'lators, of

which the following is a specification.

My invention relates to that class of devices usually termed insufflators.

It is the object of my invention to provide an insufflator that is simple and economical in construction, that is easily cleaned, and that is capable of directing a predetermined quantity of medicine to either nostril and a predetermined but varying quantity to both nostrils at the same time.

My device is especially serviceable in the application of powders after the throat and nasal passages have been cleaned in the treatment of disease for the purpose of applying a soothing or healing drug to the afflicted parts and may also be used for applying liquid medicines.

Myinvention consists in providing a device with which both nostrils may be treated at. the same time and by which both nostrils are practically closed to the outside air, so, that the person in blowing through myinsuffiator forces the drug therein to the innermost passages reached from the nostrils; further, in so constructing my insuffiator that a predetermined and different quantity of medicine or drug may be simultaneously blown into each nostril, and, further, in the parts and in the construction,arrangement, and combinations of parts hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of my device. Fig. 2 is an end elevation of the same with the flexible tube omitted, and Fig. 3 is a detail in section on the line w a; of Fig. 2.

I prefer to make my improved device, with the exceptionof the flexible tube, of glass, although it is obvious that other substances may be used.

My device consists, preferably, of a pair of tubes 1 1, adapted to be placed into the nostrils and of such size as to substantially fill the same, so that outside air may be excluded from the nostrils when the powder or drug is applied. The tubes 1 1 connect at a neck 2 and preferably merge into a single tube 3, adapted to have a flexible tube 4 attached thereto, terminating in a mouthpiece 5, adapt-. ed to be placed in the mouth for blowing,

therethrough. The tubes -1 l are preferably perpendicular and the tube 3 horizontal, with a slight. depression 6 between'the two for, the

more ready reception of the powder or substance to be blown into the nostrils.

In nasal diseasesit is frequently the case that a certain specified quantity of medicine 1or drug is required for one nostril, difiering from the quantity required for the other nostril. The application of the medicine is also more easily and pleasantly applied and the best results are also obtained when the medicine is applied to both nostrils simultane-,- The medicine it is necessary to ap the medicine to enter both nasal passages.

simultaneously and, if desired, in varying quantities, and the nostrils being practically closed except through the tubes causes the medicine by the force of the blowing and the position of the valves between the nose and mouth to reach the romotest nasal passages and the seat of the disease, and the mouth upon being immediately thereafter opened, with the tubes still in the nostrils, draws the medicine into the throat-passages for the cure of throat troubles,.tl1e application to nose or throat being regulated to a nicety by the relative length or force of exhalation and subsequentinhalation. In order to regulate the quantity of medicine to be received by each nostril, I provide the depression 6 with a web 7, dividing the same into two compartments 8 9, one communicating with one of the tubes 1 and the other communicating with the other of the tubes 1 and both communicating, with the mouthtube 3. Each of the nasal tubes therefore has a depression 6 between it and the inlettube 3, therebyforming twodistinct receptacles for medicine merging and extending directly and separately and without intermediate space into the inlet-tube and located below the horizontal plane of the inlet-tube.

See Fi s. 1 and 3. [he arts therefore exa p I and connectedlv therefrom; adepression be* tendingfrom the-nasal tubes 1 l to the inlettube3 form one integral piece of simple construct-ion and utile properties, the blow-tul'ie 4, con necting with theinlet-tube, being made flexible, so as to permit the mouthpiece 5 to be readily and convenient-lyplaced in; the mouth and directed to suit-able position.

In using my device the powder or medicine is introduced through the tubes 1 1 into the compartments 8 9, either in equal quantities or in varying quantities, or into bntone of the compartments, asmay be desirable for the treatment. By this construction I am enabled to regulate thequantityof and point of'application to a nieety. t

1 By appl'yinga separate tube to each nostril simultaneously, with each communicating it with the determined.quantity of medicine to be ppliedto that nostril and with both uostr simultaneously closed to the outside air, force of exhalation from, the mouth tion 'to pass throughthe tubes andcarries the powder with the current to the seat of the disease. outside air freely through one nostril while application is made only through the other,

as in old constructions, which results in inability to reach the seat of trouble.

If itis desired to introduce an equalamount ofmedicine into each nostril, an equalamount of medicine is placed in each com' nent, and the amount thus placed in each compartment is introduced into the nostril, even if the nasal passages of one nostril are more clogged than those of the other, which is not the case in old constructions, the tendency in old constructions being for the medicine to follow the course of least resistance.

My device is simple, compact, is small, and may readily be carried in the pocket, convenient for use at home or away from home.

substantially as described.
